Gray Tower Series

About the Gray Tower Series

Gray Tower is a five book romantic suspense series about a private military company, Gray Tower, Incorporated and the men and women who work there.  Their gray ops missions are executed by the best of the best, including ex-military, special forces, and the exceptionally talented.  

Each book can be read as a stand alone story with a new couple and a complete HEA ending.  However, it is highly recommended they be read in order to get the full effect.  Though there are no cliffhangers with the main story itself, you will see open-ended questions and situations that will continue on to other books as well as fun Easter eggs and inside jokes.  

These books are "open door" romances, meaning they show explicit sex scenes.  They are intended for adults eighteen and over.  They also cover serious topics, which can contain many different types of triggers.  Make sure you look at the warnings before reading if you think you may be affected.  They are fun, fast-paced, action-packed novels, but please make sure you are comfortable with the content before you jump into the world of Gray Tower.

Upcoming Sixth Book

Book Six of the Gray Tower Series, Mechanical Soldier, will be out sometime this year.  Maybe.  Hopefully.  I don't have many updates, except that the rough draft is approximately seventy-five percent complete.  It's a really good book, though.  I promise.  It's definitely worth the wait.  If you thought Manic Deception was crazy, you haven't seen anything yet!
